The magnetic field generation by a relativistic laser light irradiated on a thin target at the oblique incidence is investigated using a two dimensional particlein-cell simulation. The surface magnetic field inhibits the electron transport towards the inside plasma, when an incident angle exceeds the critical angle, which depends on the laser and plasma parameters.

This paper is aimed at analyzing the electromagnetic (EM) scattering from the twodimensional (2-D) Gaussian rough surfaces characterized by textures. Visual appearances of the stripe texture can be generated through the angle rotating in Fourier transform when the ratio of the correlation lengths in two directions is large enough. The scattering field is derived in Cartesian coordinate system t...

Based on the total internal reflection (TIR) under second Bragg incidence angle, polarization-independent two-port beam splitter grating etched in fused silica is described for the usual duty cycle of 0.5. There are three diffraction orders in the reflection: –2nd order, –1st order, and 0th order. The grating depth and period are optimized using the rigorous coupled-wave analysis (RCWA) in orde...

Total internal reflection fluorescence (TIRF) microscopy fluorescence— optical sectioning limiting the excitation volume to the close vicinity of the interface by sending the excitation light at an incident angle higher than the critical angle; usually implemented using a high numerical aperture (NA) objective. high signal-to-background for nearsurface structures monitoring plasma membrane proc...

A precision small-angle measurement system is introduced based on optical total internal reflection effect. When the incident angle of a polarized beam is larger than the critical angle, and the beam has a small steering angle in the vicinity of the critical angle, the total internal reflection will take place and a relative phased shift between the sand the p-polarized components is produced. ...

A large-sample decoupled maximum likelihood angle estimator for signals with known waveforms is presented by exploiting the a priori knowledge that the observation noise can be modeled as spatially white. We show that incorporating this knowledge improves signiicantly angle estimation accuracy over existing angle estimators for signals with known waveforms. MUSIC, ESPRIT, and MODE, do not assum...

We show that the commonly used Rayleigh-Debye method for calculating light scattering can lead to significant errors when used for describing scattering from dilute solutions of long rigid polymers, errors that can be overcome by use of the easily applied Shifrin approximation. In order to show the extent of the discrepancies between the two methods, we have performed calculations at normal inc...

We report on a systematic study of highly enhanced optical field and its induced thermal transport in nanotips under laser irradiation. The effects on electric field distribution caused by curvature radius, tip aspect ratio, and polarization angle of the incident laser are studied. Our Poynting vectors' study clearly shows that when a laser interacts with a metal tip, it is bent around the tip ...

The performance of a polarizing beam splitter based on the one-dimensional photonic crystals (1D-PCs), is theoretically investigated. The polarizing beam splitter consists of a symmetric stack of the low-index quarter-wave plates and the high-index half-wave plates with a central defect layer of air. The linear transmission properties of the polarizing beam splitter are numerically simulat...
